(PHYSX BUG WITH ATI) Fatal Error

Community Community & Industry Discussion

While playing the game Squad (new released game off of steam, uses the UE4 Engine) i can play for anywhere from 10seconds to maybe 3 minutes if im lucky. After the crash here is my error.

UE4-Squad Fatal Error has occured

my crash log at the bottom states this, I also have gotten with the devs of Squad they checked out the log and have verified other users having these issues. They stated they could not fix it on their end but it would be a UE4 Engine problem.

Fatal error!

It could very well be a a bug/error in UE4.
But, They cannot say that they cannot fix it on there end as they could delve into the source and locate the error and fix it.

This kinda irks me as they COULD fix it if they wanted. <- Source code access, Unless it was made in Blueprints in which case they would have to get a C++ programmer to look into it.

Bottom line: You are straight out of luck, Unless you consider buying the NVIDIA equivalent of your AMD GPU a fix.

HTH.

In UE4 it does not use GPU acceleration for PhysX, so it shouldn’t really matter what GPU you’re using. Most likely you just ran into a very uncommon bug that would be difficult to find a solution for.

There are a few of us having this issue with this game. I can play unreal tournament fine no issues. but when i play the game SQUAD (new game on Steam) it crashes. No one has any idea how to fix this

If it’s working in other UE4 games, then it could be an issue that the developers of SQUAD have to fix themselves. Might just be they need to use a more recent version of the engine.
